CLINCHER Application filed August 25, 1920. Serial No. 405,951.

To all whom it may concern:

Be it known that 1, WILLIAM H. woon,

a citizen of the United States, residing at rim includes two longitudinal sections, each in the form of a rin the two ring members having an inte ttingscrew threaded connection, whereby the ring members may not only be connected but ma be clamped snugly upon the bead portions of the tire. Provision is made for securely locking the engaged rim members so as to prevent accidental unscrewing thereof, such means also serving to assist in the unscrewing of the rim members.

With these and other objects in view, the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and particularly pointed out in the appended claim, it p of course being understood that changes in the form, proportion, size and minor details may be made, within the scope of the claim, without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings:

Figure l is a side elevation of a conventional form of automobile wheel and tire including the rim of the present invention Figure 2 is an enlarged cross sectional view taken through the tire, the rim and the fell of the wheel.

igure 3 is an inner face view of the tool employed for rotating one of the rim members when assembling and disassembling the rim members.

in the accompanying drawings there has been shown an ordinary wooden automobile wheel including a hub l, spokes 2 and a telly 3. The tire at is an ordinary neumatic tire provided with the usual bea s 5.

In carrying out my invention I provide two rim members 6 and 7, each in the form of a rin having an inwardly directed hook shaped ange as in the usual clincher type of rim. The rim member '2' includes at cmcular band 8, the interior surface of which is flat transversely and of a width corresponding to the width of the telly 3, the internal diameter of the band being such as to afiord a snug fitting of the band upon the folly, The band 8 is externally screw threaded at 9 with the screw threads leading inwardly from the adjacent circumferential edge of the band. At the opposite edge of the hand there is an external hook shaped circumferential flange 10 which extends inwardly a suitable distance across the outer face of the band. From about the middle and upon the outer face thereof, said band is provided with a transversely inclined portion 11 which inclines from the flange in a general direction towards the axis of the band so as to form a wedge surface as will hereinafter appear. At the base of the flange 7 there is an annular rib or shoulder 12, the inner face of which is substantially at right anglesto the interior of the band 8.

The other rim member includes aband portion 13 which is substantially triangular or wedge shaped in cross section, has an internal diameter to fit upon the threaded art of the band 8 and is internally threaded to fit the threaded part 9 of said band 8. The rim member 6 is rovided with a hook shaped flange 14 whic is a substantialduplicate of the hook shaped flange 10, and the upper surface 15 of the band member 13 is inclined reversely to the inclined face 11 of the band 8. An annular rib or shoulder 16 is provided upon the inner periphery of the band member 13, and this rib or shoulder is provided at suitable intervals with screw threaded openings, one of which is shown at 17 in Figure 2. For each of the screw threaded openings 17 there is a set screw 18 which is provided upon its outer end with a suitable head.

In using the present device, the rim memher 8 is placed sidewise upon the telly 3 from the inner side thereof with the annular shoulder 12 en aged with the adjacent side of the telly. he tire 4 is then placed upon the rim member 8 with one of its beads 5 engaged with the hook shaped flange 10.

The rim member 6 is then applied sidewise so as to insert the part 13 between the nnflanged edge of the rim member 8 and the adjacent head 5 of the tire, the screw threaded portions to which consists of ab r 19 P at one set screws 8 are then engaged with the screw,

threaded openings in the rim member 6 and are turned to bring their inner ends into snug engagement with the adjacent outer edge of the rim member-8 whereby'the two rim members will be :efiectually interlockedagainst accidental unscrewing. The set screws 18 ma be fitted to the 11m member 6 prior'or s sequent to the application of the rim member 6 to the rim member 8. Thescrewing ofthe rim member 6 upon the rim member 8 not only snugly clamps the'hook shaped flanges 10 and 14 upon 4 the beads of the tire but also draws the shoulders 12 and .16 into snug engagement with the opposite radial. walls of the felly 3 so as to hold therim snugly in placeupon the telly.

The rim members may be conveniently separated for removing the tire, by merely backing oft the several setscrews 18 so as to release the grip thereofagainst the rim member 8, whereupon-the vrim member 6 may be unscrewed and entirely removed from the rim member 8, the latter being permitted to remain upon the fell or removed theretrom as may be desired Normally the heads of the set screws project externally of the-annular shoulder 16 so as to be conveniently accessible when tightening and loosening the set screws.

Fer convenience in. tightening and releasing the rim member 6,1 provide a tool end with a suitable handle 20, and also provided adjacent its opposite end with a pair of transversely "extending fingers 21. At an intermediate portion of the bar or lever 19 there is an otlset part 22 which is provided with a seat, socket or recess 23 preferably" in the form of an opening of a size and configuration to receive the head of any one of the fastenings 18.

The tool is employed b first receiving one ofthe spokes of the w eel between the fingers 21 and then engaging the seat or recess 23 with the head of one of the fastenings 18, whereuponthe tool is em: loyed as a lever working upon one of the ngers 21 as a' fulcrum, whereby'the rim member-6 may be set up snugly against the adjacent head of the tire or backed oif therefrom. lit will now be understood that the set screws 18 not only interlock the two rim members but also serve as shoulders, abutments or the like for use in applying neraoee force or pressure to the rim member 6 when turningthe ,latterto tighten or release the the rim and firmly brace the rim members against transverse stresses. The rim member 8 is only as wide as thefelly, and the interengagement between the rim members is within the transverse limits of the folly,

Bib

which produces a verysnug and compact arrangement, and the interconnected parts of the rim members are backed up. by the fell V hat ll claim is:

A clincher rim including two separable rim members, one rim member being in the form of a band having its inner periphery straight transversely thereof, one edge or said rim member being provided with an external annular hook-shaped flange overhanging the rim member, said edge of the rim also bein annular shoul er, the outer peripher rim member being externally screw-threaded at the opposite edge of the member and inclined transversely adjacent the hook provided with an internal of the.-

shaped flange, the other rim member being;

in the form of a band which is wedge shaped in cross section and internally screwthreaded to fit the a externally screwthreaded portion of the first mentioned,-

band, the second mentioned band.beingpro'.

vided at its outer edge with an'erternal.

annular hook-shaped flange overhanging the band, the said band also being provided at its outer ed e with an internal annular shoulder exten ing transversely across the adjacent edge of the first mentioned band and also projecting beyond the inner periphery thereof, and a set screw extending through the shoulder of the second-menjacent edge of the first mentioned band, the

ead of the set screw projecting externally of the rim member and constituting a shoulder or abutment for use in assembling and disassembling the rim members.
